OIL DISPENSER.

Application led February 2, 1928. Serial No'f85,577. .i

This invention reltes to certain new and useful improvements 1n o1l dispensers and has forits primary object to provide an oil dispensing tank wherein oil under air pressure is elevated from a lower supply tank to an elevated discharge nozzle. e

A further object of the invention is to providean oil dispenser wherein a drum or tank is divided into a plurality of separate compartments for containing oils of diierent grades with a single airpressure device associated with the several compartments for raising the-oil thru separate discharge nozzles associated with the separate compartments. c l

A further object of the invention is to provide an oil dispenser of the type above set forth wherein a protective hood overliesthe dispenser and with a closing screen or sleeve vertically slidable upon thel container for the oil and adapted to be elevated when the dispenser is out of use and to belocked to the hook in enclosing relations relative to the dispensing nozzles. L

With the above and otherobjects in 'view that will become apparent as the nature ofv the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, 'wherein like reference characters designate like parts throughout the several views,

Figure 1 is a side elevational view of an oil dispenser constructed in accordance with the present invention,

Figure 2 is a vertical longitudinal sectionalview taken on line 2- 2 of Fig. 1 showing ,0 the separate oil com artments of the tank,

the oil, pipesextending from the separate compartments to the separate delivery-noz zles and the counterbalanced sleeve or jacket enclosing the oil tank and to be elevated into 5 engagement with the hood for enclosing the dispensing nozzle, f l .Figure 3 is a horizontal sectional view taken on line 3-3 of Fig. 2 showing 'the pipe connections extending between the separate 0 tzlmk compartments and the dispensing-noz- Figure 4 is a vertical longitudinal sec'- tonal view, similar to Fig. 2 showing the dispensing nozzles in section and the air sup-l 5v ply pipe for charging each'oil compartment for raising the o il therein to the dispensing nozzles, and

Figure 5 is a cross-sectional view taken on line 5 5 of Fig. 4 showing the communication between the air pipe and each oil compartment.

The oil dispenser; embodies a cylindrical tank having aside wall 1, a bottom wa1l2 and a top wall 3, the tank, being preferably dlvided into four compartments@ by the crossed vertical partition Walls 5 shown in section in Fig. 5.

' A cover structure orhood overliesthectank and is disposed upwardly thereof, a pair of tubular members 6` arranged opposite each other and adjacent the side v)Nall 1 of the tank extending `downwardly throught adjacent 'compartments 4 to be anchored at their lower ends with an oil-tight connection with the. bottom wall 2 Vof the tank. The upper 75 extending ends of the tubular members 6 are y attached to 'brackets 8 carried by the `de pending Aannular fiange 9 adjacent the peripheral edge of the c 'cal `cover or hood 10. The oil dispensing nozzles being disposed upwardly of the tank com artments 4 and beneath the hood 10 and it ing 'desirable to lock the tank by bridging the space between the upper end bf the tank and the hood with anenclosing jacket or the like, there is rovided a ytubular jacket l1 verti- `cally sli able `upon the side wall 1 of the tank with the'upper end of, the jacket at op--fv posite' sidesthereof adjacent the tubular vmer'nbers 6 havingeable or chain connec- 90 tions 12 with counterweights 13 slidable iny the tubular membersl with the chain 12 passing over a shezve block 14 journaled in the bracket 8 andentering the upper end of the tubular member 6 through the side opening 15 formed therein as clearly shown 'in Fig. 2. When the jacket l1 is elevated, the hasp 16 on the bracket 8 engages the staple 17 on theupper edge of the jacket and a padlock pr p other securing means attached tothe stapleI 100 locks the jacket at its rlimit of upward movement. in enclosingrelations with the Oil .dispensing nozzles. Y 1

Eachgof 'the separate oil compartments 4 of the tank has a filling opening in the wall 3 .that is closed by a pluglS and an 'discharging pipe 19 extends into each compartment through the upper wall 3 and terminates adjacent the bottom wall 2 thereof.

The upper projecting ends of the delivery ,110-

pipes 19 are enclosed by the tubular ,mem-

er 20 supported on the top wally 3 of the tank while the upper end of the tubular member 20 is provided with an enlarged head 21 adjacent the hood 10 and dis osed centrally beneath the same. The de ivery pipes 19 are enclosed by the tubular member v 20 and enlarged head 21 and the upper ends of said ipes 19 are directed outwardly as at 22 and pass through openin s in the sides of the enlarged head for delivering oil to difslpensing nozzles 23, each of which is provi ed with a controlling valve 24.

An air pressure device is associated with the several oil compartments4 of the tank and includes a lead-in pipe 25 attached to a. valve. casing 26 set into the bottom wall' 2 of the tank vadjacent the side wall 1 thereof in one of the compartments, the"k valve casing containing a check valve 27 and further having an air delivery pipe 28 extending upwardly into the tank with a circular horizontal' section 29 disposed' adjacent to and.

beneath the top wall 3 of the t-ank that is disposed in each of the compartments and passes through openings provided in the partitions 5 as shown in Figs. 4 and 5. The circular section 29 of 4the air supply pipe is provided with a series of outlet openings 30, each communicating with a compartment 4 so that air delivered to the'upper ends of the compartments ,will force th oil therein downwardly and upwardly through the deliver pipe 19 to the dispensing nozzles 23.

0i of different grades or qualities are supplied to the Yseveral com artments 4 through the filling openings c osed by the plugs-18 and'iair pressure delivered through the pipe 25 to the circular pipe section 29 discharging throu h the openings 30 into the u pper end of eac compartment causes the oil to flow upwardly through the delivery ipes 19 to the dispensing nozzles 23, the

Y.discharge thereof being controlled by the valves 24. The chamber portions of the dispensing nozzles 23 Vmay be of an area to contain a certain amount vof oil, such as a uart or the like, while` the supply of oil t@ t e dispensin nozzle is automatic in its nature, dependent upon the supply of compressed air. When the oil dis enser is out of use, the jacket 11 is eleva such movement' being assisted by the counterweights 13 bein lowered in the tubular member 6 for co ning the dispensing nozzle with the upper end of the jacket locked to the hood 1 u While there is herein sbown'and described the preferred embodiment of the present 1nvention it is, nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed is 1. In an oil dispenser, a base einbodyin a storage tank divided vertically into ap urality of oil compartments, an oil delivery pipe extending upwardly from each coinpartment, a dispensing nozzle for each pipe disposed above the tank, and a compresse air supply pipe having a horizontal portion in the upper end of the tank communicating with each compartment.

2. In an oil dis enser, a base embodying a storage tank divi ed by crossed vertical partitions into a plurality of oil compartments, an oil delivery pipe extending upwardly from each compartment, said oil delivery pipes being grouped at the point of crossing of the partitions, a dispensing nozzle for each pipe, means for elevating the oil from the compartments to the dispensing nozzles, and an inclosure for the oil delivery pipes rising centrally from the top of the tank with the dispensing nozzles disposed outwardly thereof. n

3. In an oil dispenser, a base embodying a storage tank divided vertically into a plurality of oil receiving compartments, an oil delivery pipe extending upwardly from each compartment, a' dispensing nozzle on the upper end of each pipe, means for elevating the oil from the com artments to the dispensing nozzles, a hoo supported above the tank and nozzles and a manually positionable closure for the space between the top of the tank and the hood adapted to surround the oil delivery pipes and nozzles.

4. In an oil dispenser, a base embodying a storage tank adapted to rest upon the ground and divided lby partitions into a plurality of oil compartments, an il delivery pipe extending upwardly from each compartment and supported by the tank, a downwardly discharging dispensing nozzle on the upper end of each pipe, said nozzles being disposed directly above the top of the tank, and means to eiiect delivery of oil from an desired compartment through the associate delivery pipe and dispensing nozzle.
